I've had a Facebook for 5 years, and a Myspace before that. I've never had any telemarketing calls, nor any signs of my identity being stolen. I don't mind if marketers are using my information to advertise me, at least they're adversing something I might be intrested in besides Penis Enlargment pills. There is nothing on my Facebook(or anywhere on the net that I posted) would ever put my job in jeopardy.

Oh and by the way: if you REALLY feel that way about it, then why not put up live internet cameras in your bedroom so we can watch you have sex with your wife?

That is a terrible way to view the world. I've worked on several *real* projects that were not written in C or C++. Hell there's quite a bit of popular software out there used in the real world that were not written in C or C++.
